Amazing art style and the pretty good audio design gives it a really nice atmosphere. Overall interesting setup as well.
Now some issues though: looks like you the border splitting the aim between left and right is positioned based on the default width of the window, so on full screen on a higher resolution monitor, you need to place the cursor on the far end of the left side of the window in order to aim left.
Also the birdzilla monster had so much smaller hitbox, than the collision box, that I wasn't able to reach it with the spear. Is this on purpose?
But still overall this was a pleasant experience.
